Low-momentum particle identification with SVD, operational activities of SVD and a study of 𝚼(𝟒𝐒)→𝐁𝟎𝐁̅𝟎 at Belle II

	Particle identification (PID) constitutes an integral part of all high-energy physics experiments. Belle II is no exception! In this talk, I will discuss our group’s efforts to identify low-momentum charged particles and improve their detection performance by including the specific ionization information from the silicon-strip vertex detector (SVD) into the overall Belle-II PID framework. I will highlight the changes and improvements in last two rounds of calibration I was directly involved in. In the latter part of the talk, I will discuss our ongoing work on the precision measurement of the Υ(4S)→B0B̅0 branching fraction using the data recorded by Belle II. The results of this work would be helpful in various branching fraction measurements involving B mesons. I would conclude by summarizing SVD’s overall performance after the first long shutdown run period and briefly discussing our group’s ongoing operations-related activities at KEK.
